Hi Tabrez, Thank you so much for sharing the information.
I am very new and don't know much about Alfresco.
Actually I installed the Alfresco Community 5.2 version. Then I checked the available Workflow and found that there is no Workflow for multiple stages. For example, Requester upload document and then Approver 1 approve it. And then it will go to second level approver and so on.
On Internet, I found that we have to create Custom Workflow for such requirement.
